Using jquery and repeater together with ClientID

Posted 21 April 2013 - 05:15 AM

Hi everyone;

I examine lots of blogs answers about my question also I found some solution from this sites and I tried all of them. But I don't know why is it? These solutions are not fix my problem I get errors always.
Finally, I found a solution that I recognize that is true, because in many place this solution is accepted. But this cannot solve my problem again.

$("#<%=plusBttn.ClientID%>")

I get this error when I tried this solution : plusBttn does not exist in the current context.

I use predictable mode for client mode for my buttons and textbox. Simply, I want to change quantity , which shown in a textbox(QuantityTxtbx), with control my buttons (minusBttn for decrease the value of quantityTxtbx value and plusBttn similarly use for increase the value)

Actually my problem is in the find my controls by using ClientID in jscript.
